Conflict: server/match/player/basics.js imports (W5G's checkNotOwned + W5I's msg / dn). data/i18n/en.json rebuilt on the merged data (tools/build-i18n.mjs --offline): the 自选 data adds texts of CN-only operators and modules the EN client lacks, so coverage is 97.6 % (skills 95.9, talents 95.1); the coverage floors in test/i18n-data.test.js and docs/I18N.md say so. Golden unchanged; i18n / lobby / match / ui suites 1144/1144 after the rebuild, i18n e2e 1/1.
NOTICE.md and THIRD-PARTY-NOTICES.md credit @YuriRestia (PR #70) for the English UI strings and fallback
translations, note that PR #70's ak-spa-database.pages.dev texts are not used and that arknights.wiki.gg is
CC BY-SA 4.0, and name the EN data mirrors (ArknightsAssets/ArknightsGamedata, Kengxxiao/ArknightsGameData_YoStar).
DATA.md: data/i18n/en.json is written by tools/build-i18n.mjs (rerun after a text-changing build).
PLAYING.md: the 中文 / English switch.
